NAME
dans-gdal-scripts - A GDAL add-on set of utilities o gdal_contrast_stretch - Contrast stretch and conversion from 16-bit to 8-bit o gdal_dem2rgb - Generate hillshaded images from DEMs o gdal_raw2geotiff - Convert raw binary files into GeoTIFFs o gdal_get_projected_bounds - Project a polygon and return its bounding rectangle o gdal_trace_outline - Trace the outline of an image and generate WKT or Shapefile o gdal_merge_vrt - Merge individual bands into a single VRT image o gdal_merge_simple - Merge individual bands into a single GeoTIFF image (8-bit only) o gdal_landsat_pansharp - Pansharpening - works best for Landsat 7 images o gdal_wkt_to_mask - Generate a bitmap of the area covered by a polygon o gdal_list_corners - Prints raster geocode information in YAML format (similar to gdalinfo but gives YAML) o DESCRIPTION
This manual page documents briefly the Dan's GDAL Scripts set of commands. You can get a synthetic description of accepted options and command line arguments by using -h option with every command. This set of tools is based on the GDAL/OGR library and provides some useful simple manipulation of geo rasters and satellite data. Do not buggy GDAL team for possible issues with this software, this is a contrib- uted set of programs. SEE ALSO

NAME
gdal_translate - gdal_translate converts raster data between different formats SYNOPSIS
gdal_translate [--help-general] [-ot {Byte/Int16/UInt16/UInt32/Int32/Float32/Float64/ CInt16/CInt32/CFloat32/CFloat64}] [-strict] [-of format] [-b band] [-mask band] [-expand {gray|rgb|rgba}] [-outsize xsize[%] ysize[%]] [-unscale] [-scale [src_min src_max [dst_min dst_max]]] [-srcwin xoff yoff xsize ysize] [-projwin ulx uly lrx lry] [-a_srs srs_def] [-a_ullr ulx uly lrx lry] [-a_nodata value] [-gcp pixel line easting northing [elevation]]* [-mo "META-TAG=VALUE"]* [-q] [-sds] [-co "NAME=VALUE"]* [-stats] src_dataset dst_dataset DESCRIPTION
The gdal_translate utility can be used to convert raster data between different formats, potentially performing some operations like subsettings, resampling, and rescaling pixels in the process. -ot: type For the output bands to be of the indicated data type. -strict: Do'nt be forgiving of mismatches and lost data when translating to the output format. -of format: Select the output format. The default is GeoTIFF (GTiff). Use the short format name. -b band: Select an input band band for output. Bands are numbered from 1. Multiple -b switches may be used to select a set of input bands to write to the output file, or to reorder bands. Starting with GDAL 1.8.0, band can also be set to 'mask,1' (or just 'mask') to mean the mask band of the 1st band of the input dataset. -mask band: (GDAL >= 1.8.0) Select an input band band to create output dataset mask band. Bands are numbered from 1. band can be set to 'none' to avoid copying the global mask of the input dataset if it exists. Otherwise it is copied by default ('auto'), unless the mask is an alpha channel, or if it is explicitely used to ben a regular band of the output dataset ('-b mask'). band can also be set to 'mask,1' (or just 'mask') to mean the mask band of the 1st band of the input dataset. -expand gray|rgb|rgba: (From GDAL 1.6.0) To expose a dataset with 1 band with a color table as a dataset with 3 (RGB) or 4 (RGBA) bands. Usefull for output drivers such as JPEG, JPEG2000, MrSID, ECW that don't support color indexed datasets. The 'gray' value (from GDAL 1.7.0) enables to expand a dataset with a color table that only contains gray levels to a gray indexed dataset. -outsize xsize[%] ysize[%]: Set the size of the output file. Outsize is in pixels and lines unless '' is attached in which case it is as a fraction of the input image size. -scale [src_min src_max [dst_min dst_max]]: Rescale the input pixels values from the range src_min to src_max to the range dst_min to dst_max. If omitted the output range is 0 to 255. If omitted the input range is automatically computed from the source data. -unscale: Apply the scale/offset metadata for the bands to convert scaled values to unscaled values. It is also often necessary to reset the output datatype with the -ot switch. -srcwin xoff yoff xsize ysize: Selects a subwindow from the source image for copying based on pixel/line location. -projwin ulx uly lrx lry: Selects a subwindow from the source image for copying (like -srcwin) but with the corners given in georeferenced coordinates. -a_srs srs_def: Override the projection for the output file. The srs_def may be any of the usual GDAL/OGR forms, complete WKT, PROJ.4, EPSG:n or a file containing the WKT. -a_ullr ulx uly lrx lry: Assign/override the georeferenced bounds of the output file. This assigns georeferenced bounds to the output file, ignoring what would have been derived from the source file. -a_nodata value: Assign a specified nodata value to output bands. Starting with GDAL 1.8.0, can be set to none to avoid setting a nodata value to the output file if one exists for the source file -mo 'META-TAG=VALUE': Passes a metadata key and value to set on the output dataset if possible. -co 'NAME=VALUE': Passes a creation option to the output format driver. Multiple -co options may be listed. See format specific documentation for legal creation options for each format. -gcp pixel line easting northing elevation: Add the indicated ground control point to the output dataset. This option may be provided multiple times to provide a set of GCPs. -q: Suppress progress monitor and other non-error output. -sds: Copy all subdatasets of this file to individual output files. Use with formats like HDF or OGDI that have subdatasets. -stats: (GDAL >= 1.8.0) Force (re)computation of statistics. src_dataset: The source dataset name. It can be either file name, URL of data source or subdataset name for multi-dataset files. dst_dataset: The destination file name. EXAMPLE
